RIVET-FEEDING MECHANISM.
Application filed October 22, 1925. Serial No. 64,070.
This invention relates generally to a device for delivering rivets onc-at-a-time and in unbroken order to a rivet setting machine.
A general object of the invention is to provide an improved rivet feeding mechanism of the hollow pick-up wheel type in which the rivets are fed into the pick-up member which in turn delivers them one-at-a-tin'ie to the machine.
The invention includes a cup-shaped pickup member provided along its marginal portion with a series of rivet receiving slots so formed and arranged as to receive individual rivets which are properly disposed for the purpose in a mass of rivets resting on the slotted portion of the wheel as it rotates.
A particular feature of the invention resides in the construction of the hollow pickup member, the inner surface of which is provided with a series of steps whereby the mass of rivets within the pick-up member is broken up and delivery of the rivets is facilitated.
Other features of the invention will ap pear as the description proceeds.
In the drawings, in which a preferred embodiment of the invention has been seleot-ed for illustration Fig. 1 is a cross section of the rivet feeding device; and
Fig. 2 is a face View of the picleup member.
Referring to the drawings for a more de tailed description of the invention, a rivet feeding device is shown which includes a supply hopper 10. A shaft 11 is journaled in a boss 12 formed on the hopper. The rivet sorting and arranging member or pick up member, 13 is cup-shaped and is clamped against .a collar l t on the shaft by a resilient washer 15 and nut 16. The rim of the pick-up member is provided with a series of rivet-receiving slots 17 which receive the individual rivets and deliver them to the receiving channel 21.
The peripheral wall of the pick-up member is outwardly flared, but instead of having a gradual slope is provided with a series of flat surfaces, or steps, arranged parallel to the axis of rotation of the pickup memher. The mass of rivets delivered from the supply hopper is tumbled about within the pick-up member by rotating the shaft 11, and as a result the rivets are caused to fall toward and into the slots 17. It has been found that if the outer wall of the pick-up member is form-ed with a gradual slope the rivets tend to mat into a somewhat solid mass the entire weight of which presses the mass toward the receiving slots. And as a result the sorting of the rivets into the slots is impeded.
This objectionable action is avoided in the present invention by forming the peripheral wall of the pick-up member with the flat steps 18, 19 and 20. Each of these steps car ries the entire weight of a certain number of the rivets in the drum. Hence the rivets do not form into a single mass and the rivets on the lower step 20 can move freely to fall into the receiving slots.
What is claimed is 2- 1. In a rivet feeding device, a hollow rotatable pick-up member the inner peripheral wall of which is formed with a series of steps of substantial width disposed substantially parallel to the axis of rotation.
2. In a rivet feeding device, a rotatable cup-shaped pick-up member having receiving slots formed in the margin thereof and having its inner peripheral wall formed with a series of steps of substantial width disposed substantially parallel to the axis of rotation.
8. In a rivet feeding device, a rotatable cup-shaped pick-up member having receiving slots formed in the margin thereof and having its inner peripheral wall formed with a series of short flat steps arranged parallel to the axis of rotation of the drum.
4. In a rivet feeding device, a rotatable hopper, the inner circumferential wall of said hopper being provided with a plurality of circumferential shoulders separating steps of substantial width disposed substantially in a horizontal position.
In testimony whereof I afiix my signature.
EDWIN B. STIMPSON.
